HAT SWEAT AND PROCESS OF MAKING THE SAME.

Original application led August 4, 1924, Serial No. 730,015. Divided andthis application illed March 1, 1926. Serial No. 91,530.

The invention relates to new and useful improvements in hat sweats andthe process of making the same.

It has long been customary to stitch to a hat sweat a reed which is usedin connection with the securing of the hat sweat to the hat.

An object of the present invention is to provide a hat sweat having anedge covering which is formed of stitching threads and wherein one ofthe threads lies along the edge of the hat sweat and is secured theretoby the enchained loops of the stitches, so that said thread can be usedfor the securing of the hat sweat to the body of a hat.

A further object of the invention is to provide a. process of forming anedge covering for a hat sweat, wherein the edge cove'ring stitches maybe passed through the hat sweat at a considerable distance back from theedge thereof and one of the stitching threads of the concatenatedover-edge stitches laid straight and taut along the edge of the hatsweat, whereby said thread may be used for securing the hat sweat to thebody of the hat.

In the drawings which show by way of illustration one embodiment of theinvention- Y Figure 1 is a plan view of a hat sweat embodying myimprovements, and Fig. 2 is a perspective view showing the method ofholding or bending the hat sweat and the forming of the over-edgestitches therethrough.

The invention is directed broadly to a hat sweat having edge coveringstitches, the loops of which are passed through the body portion of thehat sweat at a considerable distance back from the edge of the hatsweat. These loops are brought to the edge of the hat sweat and extend ashort distance beyond said edge. The thread in which the loops areformed is likewise brought to th'e edge of the hat sweat and aslightdistance therebeyond. The looper thread passes through the needle threadloops laid at the edge of the hat sweat and around the shank of the nextneedle loop, so that said looper thread may be drawn taut and will passstraight along the edge of the hat sweat and will be woven with theneedle thread loops. Referring more in detail to the drawings, myimproved hat sweat is indicated at 1 in the drawings. The edge coveringstitches are indicated at 2. These covering stitches are formed from theneedle thread 3 and the looper thread 4. The needle thread is carried bya needle 5, and the looper thread is carried by a looper 6. The hatsweat l is bent along the line 7 which is some distance back from thefree edge 8 of the hat sweat, and this bent portion of the hat sweat isdeflected so as to lie substantially parallel with the path of theneedle 5, which needle moves in a horizontal plane. The needle passesunderneath the bent portion of the hat sweat, and penetrates said hatsweatv at points 9, 9. The looper 6 has an oscillatin movement so as toenter the needle thread loop where the needle emerges from the hatsweat. Saidlooper is then moved laterally across the free edge 8 of thehat sweat, and is depressed so that the needle 5 will pass between thelooper thread 4 and the body portion 10 of the looper. The needle passesbetween the thread and the body of the looper when it moves orward'toenter the hat sweat for the next stitch. The looper is then retracted,and the looper thread is left encircling the needle 5. When the needleis withdrawn from the hat sweat, it will likewise withdraw from betweenthe looper and the looper thread and will leave the shank of the formedneedle loop lying over the looper thread. As has already been noted, thelooper moves through the needle loop when it rst emerges from the hatsweat, and of course, leaves a loop therein. The threads' are now sointerlocked, that when the stitches are set with considerable tension onthe looper thread, said looper thread will be laid straight andsubstantially taut along the edge of the hat sweat. The looper thread iswoven, so to speak, into the overedge threads passing over adjacentstrands 11, l1 of the thread loops, and underneath the i stitches.

shank portion 12 of a needle thread loop. The edge of the hat sweat iscovered by the needle thread loops on one side and the shank of theneedle'thread loops on the other side, plus the connecting needle threadloop extending from one stitch formation to the next stitch formation.rlhe needle thread loops are carried to the edge of the hat sweat and alittle beyond, while the shanks are likewise laid on the other face ofthe hat sweat. Thus it is that the looper thread may join or tietogether t-he needle thread loops and the shanks of the needle threadswith the connecting thread between adjacent The threads are therebyfirmly secured to the hat sweat, and are well anchored therein becausethe needle penetrated the hat sweat a considerable distance back fromthe edge thereof. rfhe needle thread covers to quite an extent both ofthe side faces of the hat sweat, and the looper thread lies as asubstantially straight continuous thread along the edge of the hatsweat. By the bending of the hat sweat as above described,

the needle, without any lateral vibration therein, is caused to enterthe hat sweat well back from the edge of the hat sweat, and at the sainetime, cooperate with the looper, both at the point where it emerges fromthe hat sweat and at the edge of the hat sweat.

l/Vhile the invention is particularly adapted for overedging a hat sweatso that it may be secured to the body portion of the hat through the aidof the overedge stitches, the covering stitches are very neat and form acontinuous edging for the material, and therefore, the invention is notlimited to the particular use stated. ft may be used fori covering theedges o f fabrics for other purposes.

One of the essential features of the covering seam or stitches for theedge of a fabric, is the simplicity of manufacture, and at the sametime, the deep anchoring of the thread loops back from the'edge of thefabric. Another essential feature consists in the arrangement ofthebites of the loop against one face of the fabric so that they projectslightly beyond the edge, and the shanks of lthe loops against the otherface of the fabric with the thread connecting or forming successiveloops slightly beyond the edge, so that the bites of the loops and theshanks of the loops may be tied or woven together and locked by thelooper thread which lies' straight'along and slightly beyond the edge ofthe material being covered.

This application is a division of my copending application Serial No.730,015,'led August 4C, V1924, wherein a Vmachine has been disclosed indetail for carrying out the process of forming the edge covering.Reference `Vmay be ina-de to said application for a further descriptionof the invention.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent, is-

l. The process of forming an edge covering for fabrics which consists inbending the edge portion of the fabric to a position at an angle to thebody portion of the fabric and covering the edge of said bent portion bypassing a threaded needle along the lower face of said bent portion ofthe fabric and penetrating thefabric substantially at the bend in thefabric, laying the needle thread loops which emerge from the fabricagainst the upper face of thebent portion with the bites thereof at theedge of the fabric,lay ing the'shanks of the needle `thread loopsagainst the lower face of the bent portion, and securing the shanks ofthe loops and the thread portions connecting the same to the bites ofthe needle thread loops by the.

looper thread which lies straight and along the edge of the fabricpassing underneath the shank portions of the loopsv and over theV biteportions thereof.

2. The processV of forming an edge covering for a hat sweat consistingin bending the edge portion of the leather of the hat sweat at an angleto the body portion of thehat sweat and passing a threaded needle underthe lower face of said bent portion and through the hat sweatsubstantially at the bend therein, passing a threaded looper through theneedle thread loops after they emerge from thel hat sweat, andmanipulating said looper and needle so as to lay the needle thread loopsagainst the face of the fabric from which they emerge, with the bites ofthe loops. at the hat sweat edge, and laying the shanks ofthe needlethread loops against the other face of the fabric, with the threadportions connecting the shanks at the edge of the fabric, and'with thelooper thread lying straight along the edge of the hat sweat, passinglunderneath the shank portions of the loops and over the bite portionsof the loops for securing the same together. Y

3. The process of forming an edge covering for fabrics which consists inpassing a threaded needle along one face 'of the fabric and through thefabric at a distance back llO from the edge thereof, laying the needleopposite side of the bite portions.

4. An edge covering for fabrics consistin-g of thread loops passingthrough the fabric back from the edge thereof, wherein the' bites of theloops are laid on one face of the fabric and project beyond the edgethereof, While the Shanks of the thread loops are laid against the otherface of the fabric and eX- tend beyond the edge thereof so that theconnecting threads of the loops lie beyond the edge of the fabric, and alooper thread se-
